Tus qauv qauv:
Daim ntawv thov
Cov khoom muaj peev xwm ua tau zoo pib polymerization ntawm qhov kub thiab tsis tshua muaj siab kom tsim tau cov kab tawm siab thiab siab molecular hnyav polymer.
Va-044 pib muaj kev pib ua haujlwm siab, qhov hnyav molecular, zoo solubility thiab tsawg residue ..
VA-044 pib yog tau los ntawm kev qhia cov pab pawg hydrophilic rau hauv cov molecule ntawm azonitrile pib, thiab muaj dej solubility zoo.Yog li ntawd, VA-044 pib yog feem ntau haum rau aqueous tov polymerization thiab emulsion polymerization ntawm polymer synthesis .Piv nrog rau cov hom dav dav ntawm azo pib, VA-044 tus pib muaj kev pib ua haujlwm siab, kuj muaj cov txheeb ze molecular loj, dej solubility zoo, thiab tsawg dua lub cev.Piv nrog rau cov inorganic persulfate thiab lwm cov dej-soluble pib, VA-044 tus thawj coj tuaj yeem ua kom muaj kev sib haum xeeb, ruaj khov thiab tswj tau cov tshuaj tiv thaiv decomposition los tsim cov linearity siab thiab siab molecular hnyav polymers.
Tsis zoo li azo nitrile cov khoom, vim hais tias nws tsis muaj cyano pawg, cov khoom decomposition ntawm VA-044 pib tsis muaj tshuaj lom.Nyob rau tib lub sijhawm, nws decomposes tsis tu ncua ntau dua li lwm tus pib, muaj kev hloov pauv ntau dua, thiab tsis muaj qhov seem lossis agglomeration tshwm sim thaum lub sijhawm txheej txheem polymerization.Nws muaj peev xwm ua tau zoo pib polymerization ntawm qhov kub thiab tsis tshua muaj siab kom tsim tau cov linearity siab thiab siab molecular hnyav polymers.Yog li ntawd, VA-044 pib yog dav siv nyob rau hauv aqueous tov polymerization thiab emulsion polymerization ntawm polymer synthesis, xws li monomer acrylamide polymerization, Initiator rau polymerization tshwm sim xws li styrene emulsion polymerization thiab monomer polymerization ntawm styrene thiab butyl acrylate.
